The library's Equipment Loan Office circulates two Elmo 16-CL projectors to patrons who have completed projection certification (see: "Circulation & Copyright" tab for more details). Additionally, the MMB screening room in the lower level of the library offers two Elmo projectors for use by certified patrons.
There is also a guide manual available for these projectors which circulates with the projectors, and is also available in the Equipment Loan Office and as a downloadable PDF.
(Note: This guide does not necessarily translate to other models of projectors, but the principle of projection remains the same.)
